RRuntimeError is a Python/rpy2 exception saying that the evaluation of R code was stopped because of an error. That error is reported verbatim (as shown above) and is: "density.default(list(4.52, 2.42, 4.5, 2.54, 9.79, 2.5, 3.96, : argument 'x' must be numeric". r.density(robjects.FloatVector(data_dict['Income'])) will likely work. A system for guessing and converting python sequences could not make it in time for the release 2.0, but will be present in 2.1.
